Resumo: | In order to reproduce and investigate the marine circulation in the coastal tidal zone, and especially its three dimensional nature, it appeared interesting to develop a numerical mode! which could take account of the real bottom topography and the variations of the free surface. Navier-Stokes equations are solved in a straight forward manner, generalizing a finite difference technique already used in two-dimensional vertical models. To test the computational program, the mode! was applied to a number of flat bottom schematic basins, where we reproduced wind driven currents and tide propagation. Then we considered the particular case of a real channel and, finally, density currents associated with a salty wall. Mode) results are compared to theoretical solutions (amphidromic point, Ekman spiral) or results obtained from other models. The first attempt to apply the mode! to a real area was for the Bay of Seine. Although certain specifie points in the numerical scheme could be improved, results seem favourable, and show that the mode! reproduces quite weil the different physical phenomena of interest in coastal areas.
